Calisthenics, Skateboarding, Instruments, Listen to music, martial arts, build stuff Weed will make everything else boring unless you have friends. Not sure what else is available for drugs but if you have a good dealer maybe try some hippy drugs, idk, do some research man.

how old are you right now? maybe you're still young.. try to have a pet. Maybe you can relate with how they feel.. At least in pets like dog,cat,fish,birds etc. you can build connections which is indeed vital for you at the moment. I hope it will help. P.S. I once lost too, but now I'm found in God's purpose.
